A fella surprise his wife while she is doing it with the mailman, the gardener or his best friend. He will yell to them: " Get the fuck outta here!" (an asking from his part to them to take the fucking act out of his bedroom and out of his sight) and will slam the door closed after they move out and do it outside.

The interjection is also known to be a good palliative to heart attack when seeing unexpected unpleasant thing.

However it didn't work for OBL. He used it as a spell against the team six guys who got in his basement: " Get the fuck outta here!" but he get shoot anyway. The team six guys appeared to be deaf dumb both.
